Every Range Rover drives all four wheels all the time, so the transfer case and differentials work as hard as the engine. Neglected oil, worn chains and failing motor actuators show up as whining, vibration at speed or a 'transfer box fault' message.
We service and rebuild transfer boxes including the chain and clutch pack, replace differential bearings and seals, and repair the electronic locking differential and its motor. Propshaft centre bearings and CV joints are checked at the same time so you leave with a silent driveline.
Transfer Case & Differentials on the Land Rover Defender
Whether it is a classic 110 or the new L663 Defender, this is the vehicle that defines the brand. We look after both, from TD5 injector looms to the very latest D300 mild hybrid and the P525 V8.
Engines we cover on this model: 2.0 Ingenium, 3.0 Ingenium P400 MHEV, 5.0 V8, 3.0 D300 diesel, classic TD5 & Puma. Production 1983 – present (L663 & classic). Faults we see most often on the Land Rover Defender include air suspension on l663 after off-road use, ingenium oil dilution on short journeys, classic td5 injector harness oil contamination, and each is diagnosed with the model-specific procedure before any parts are recommended.

How we work
Every job begins with a proper diagnosis on the lift and on Land Rover's diagnostic platform. You receive a written report, photos and a fixed price on WhatsApp before any work begins. Genuine or OE-equivalent parts are used, every repair carries a written warranty, and the vehicle is road tested before handover.
Frequently asked questions
How often should transfer case oil be changed?
Every 60,000 km in our conditions, or sooner if you drive off-road or tow regularly.
Can a transfer box be rebuilt?
Yes. Chains, bearings and actuators are all serviceable and far cheaper than a replacement unit.
What causes a driveline vibration?
Most commonly a worn propshaft centre bearing or CV joint. We check both on the lift before quoting.
